What is meant by specific heat capacity of iron is 460j kg?
To say that the specific heat capacity of iron is 460 J/kg K means that 1 kg of iron gives out or takes in, as the case may be, 460 J when its temperature changes by 1 K.
What is the specific heat capacity of the iron?
0.450
Heat Capacities for Some Select Substances
| Substance | specific heat capacity Cp,s (J/g °C) | molar heat capacity Cp,m (J/mol °C) |
|---|---|---|
| iron | 0.450 | 25.09 |
| lead | 0.129 | 26.4 |
| lithium | 3.58 | 24.8 |
| mercury | 0.14 | 27.98 |
What does it mean when we say specific heat capacity of iron is 450J kg C?
Specific heat capacity in J / kg °C The greater the mass of the substance then the greater amount of energy needed to raise the temperature. For example a 5kg mass of iron would need 2250J (5 x 450J).
What is the specific heat of iron in J kg C?
Specific heat capacity of materials
| Material | J/kg.K | J/kg.°C |
|---|---|---|
| Helium | 5192 | 5192 |
| Hydrogen | 14300 | 14300 |
| Ice | 2090 | 2090 |

What is mean by specific heat capacity of the substance is 910 kg degree Celsius?
When we calculate this value to two significant figures, we find a result of 910 joules per kilogram degrees Celsius. This answer means that in order to heat one kilogram of asphalt concrete by one degree Celsius, we would need to input 910 joules to the concrete. That’s the specific heat capacity of the asphalt.
What does specific latent heat mean?
Specific latent heat is the amount of energy required to change the state of 1 kilogram (kg) of a material without changing its temperature. latent heat of fusion – the amount of energy needed to melt orfreeze the material at its melting point.
What is the specific heat of steel?
420 J/(kg°C)
The specific heat of steel is 420 J/(kg°C).
What is the specific heat capacity of water in J kg C?
4,200 Joules per kilogram per degree Celsius
The specific heat capacity of water is 4,200 Joules per kilogram per degree Celsius (J/kg°C). This means that it takes 4,200 J to raise the temperature of 1 kg of water by 1°C. Lead will warm up and cool down fastest because it doesn’t take much energy to change its temperature.
What is the specific heat capacity of a 5kg iron?
A 5kg block of iron with a specific heat capacity of 450 J/kg C receives 0.03MJ of energy. What is the temperature rise of the iron? How do I get rid of grey hair naturally without dye? A permanent anti-grey hair treatment that restores hair natural color without artificial dyes/pigments.

What is the relationship between specific heat and temperature change?
The specific heat is the amount of heat enregy per unit mass required to raise the temperature by one degree Celsius. The relationship between heat and temperature change is usually expressed in the form shown below where c is the specific heat . Specific Heat Capacity Conversions: 1 Btu/(lb-°F) = 4186.8 J/(kg-°K) 1 Btu/(lb-°F) = 4.1868 J/(g-°C)
What is the SI unit of heat capacity?
Heat capacity is denoted by the symbol C with the S.I. unit of J/K (Joule/Kelvin) [2]. When the heat capacity of a substance is divided by its mass, the resultant is the value of the substance’s specific heat capacity, an intensive property that is not dependent on sample size or mass [2].
